# TED Ed is appropriate for assessing a student’s comprehension of a specific video that the student has watched outside of class. It explicitly recognized that many of the questions that you might raise will not be computer graded.
# Flubaroo is a tool that is well-integrated with Google Docs; it would be easy to administer a test using this tool at a school that uses Google Apps for Education.
# QuizStar is appropriate for any sort of out-of-class testing in which the questions need to include more than text; it also provides a good tool for tracking and managing grades.
# Quipper is for a situation in which the teacher is not interested in tracking student grades but is more interested in motivating the students to learn a topic.
